SPECIFICATION forming part of Letters Patent No. 788,094, dated April 25, 1905.

Application filed Decemycr 15,1902. Serial No. 135,208.

Be it known that l, Jonx B. CLnRuoxr, a citizen of the United States, residing in W'illiams Bridge, in the county and State of New York. have invented an Improvement in Devices for Attaching Chains or Cords, of which the following description, in connection with the accompanying drawings, is a specifica tion, like letters on the drawings representing like parts.

This invention relates to a device with which the chains or cords employed for suspending window-weights may be fastened to the window-sash, and has for its object to provide a simple and efl'icient fastening de vice which can be applied to the windowsash in a minimum time and at a minimum expense.

The particular features of this invention will be point-ed out in the claims at the end of this specification.

Figure 1 represents in vertical section a sufficient portion of a window frame and sash provided with a chainfastening device embodying this invention to enable it to be understood: Fig 2, a vertical transverse section on the line 2 2, Fig. 1, looking in the direction of the arrow thereon; and Figs. 3 and r, sectional details, on an enlarged scale, of the fastening device shown in Figs. 1. and 2, Fig. -l being a section on the line -l -l, Fig.

Referring to Figs. 1 and 2, (1 represents the window casing provided with the usual pocket I) for the weight, (not shown) but which has attached to it a chain or cord c, which is passed over a pulley (7 and is connected with the window-sash c. The parts referred to may be of any suitable or usual construction. In accordance with this invention the chain or cord c is secured to the window-sash e by a device, as will be described. which simple, inexpensive, and efficient in operation and one which can be assembled in the shop and applied to the win- (low-sash while disconnected from the chain or cord c. thereby enabling the window-sashes to be equipped with the fastening devices before they are placed in position, if desired.

The fastening device referred to may be made as herein shown, and consists, essen tially, of a cylindrical body or shellf, of metal or other suitable material, having on its inner circumference an annular groove g (see Figs. 3 and 4) for the reception of a curved piece 71, preferably a wire of substantial cross-section, which for the best results is made in the form of a ring having free ends, one of which is extended inward to form an arm i for a purpose as will be described. The cylindrical body portion or shellfis provided with a slot or opening j, which extends across the annular groove and is made sullir'fiiently large for the passage through it of the looped end of the chain or cord c, through which is passed the locking-piece 71, as represented in Figs. 3 and 4. The locking-piece 71 in practicev is frictionally held in its groove, but can readily be moved therein by hand, which permits the said locking-piece to be placed in its shell or body portion before the latter is applied to the windowsash. To apply the shell or bodyf, the workman bores a cylindrical hole or socket in the sash, so as to communicate with a longitudinal groove or slot lr, which is now commonly provided for the reception of the chain or cord c, and then forces or drives the shell or bodyfinto said hole or socket. The fastening device can thus be applied to the windowsash at any time, and, if desired, the chain can be connected therewith prior or subsequent to the fastening device being applied to the window-sash. To secure the chain or cord to the fastening device, it is only necessary for the workman to turn the locking ring-or piece 72. around in its groove until the space between its ends registers with the hole or opening in the body or shcllf, after which a link of the chain or the looped end of the cord is passed through the said slot or opening, and the locking device or piece is then turned so as to pass its free end 5 through the loop in the chain or cord. In order to prevent accidental disengagement or withdrawal of the locking-piece from the loop of the chain or cord, means are provided for preventing the locking-piece from turning in its groove sufficiently to withdraw its free end from the loop of the link, and in the present instance a screw 6 is employed for securing the shell to the. window sash, which screw is ment of the said ring to be engaged by said passed through a suitable opening in the end l or head 7 ofsaid shell from the inside, and the said end wall or head of the shell and the groove 9 are so distanced from each other that the head of the screw 6 may project into the path or plane of movement of the arm "L, (see Fig. 4,) thereby limiting the rotary movement of the locking-piece and preventing accidental unlocking of the same from the chain or cord.

I claim 1. In a fastening device of the character described, in combination, a cylindrical shell or body provided with a slot in its circumference and having a head, a metal ring fitted within said cylindrical shell or body to engage the circumference thereof and provided with an inwardly-extended arm, means on the cylindrical body or shell for retaining said metal ring against longitudinal movement within said shell or body, and means on said head projected into the path of movearm and restrict movement of the ring in one direction, substantially as described.

2. In a fastening device of the character described, in combination, a cylindrical shell or body having a slot in its circumference, a metal ring fitted within said shell to engage the circumference thereof and provided with an inwardly extended arm, means within said shell to retain said ring against longitudinal movement therein, and means within said shell for engaging the arm on said ring to restrict movement of the ring within the shell in one direction, substantially as described.

'3. The combination with a window provided with a cylindrical socket in its sash and with a longitudinal groove or slot extended from said socket, of a cylindrical shell of substantially the diameter of said socket and fitted therein, said shell having a slot in its circumference, and means on its inner circumference to retain a metal ring, said metal ring engaging the inner circumference of said shell and provided with an inwardly extended arm, and a screw for fastening said shell in its socket, said screw cooperating with the arm on said ring, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
